In a Proportions game I was playing recently I ended up starting right next to a neutral race. Found them on the 2nd turn, they declared war on me but since they were neutral I didn't really bother with them.

Tried to get a Trade Alliance with them after a few years, no luck. Figured I didn't need them anyway and continued to not bother them (I was fighting a bloody war with a the Xi-Chung hive anyway).

Then, about 20 years after I had discovered them, they contacted me and wanted a Trade Alliance...

So apparently it takes a *long* time of not bothering them before they are willing to end the war.
